Ronda Rousey’s return to the UFC will be delayed further while she recovers from knee surgery, UFC president Dana White said on ESPN on Thursday.

Rousey recently underwent minor knee surgery to repair lingering damage, according to White. Her return will not occur earlier than December, and will likely happen later.

“She feels great, her spirits are great, she’s been training so if she fights, I’m hoping she fights in either December, if not she would probably fight at the like the New Year’s show, beginning of the year or something,” White said on Sportscenter.

Rousey has not fought since November 2015, when she suffered her first professional defeat at the feet of Holly Holm at UFC 193. Since then, Rousey has been focusing on her movie career, and is expected to film a remake to Road House this summer.

White said Rousey’s return fight will be for the bantamweight championship. Miesha Tate currently holds the belt after defeating Holm.

“If Miesha Tate’s still the champion, she'll fight Miesha Tate. Whoever has the belt is who Ronda Rousey will fight,” White said. “Injuries happen in this sport, somebody falls out and somebody else slides in, I’m not even saying Holly Holm couldn't be the champion by the time Ronda comes back.”
